The Pittsburgh Steelers selected Tennessee quarterback Joshua Dobbs 135th overall in the fourth round of the NFL draft on Saturday.

As a senior last season, Dobbs passed for 2,946 yards and 27 touchdowns and rushed for 831 yards and 12 touchdowns, but he also had 12 interceptions. As a junior in 2015, he passed for 2,291 yards, 15 touchdowns and five interceptions. He also rushed 671 yards and 11 touchdowns. Dobbs started as a true freshman and led the Volunteers to three consecutive bowl wins.

Here are three things to know about Dobbs:

1. He has a degree in aerospace engineering with a business minor. During college, Dobbs completed two internships with Pratt & Whitney, a Canadian aerospace engineering film. According to Emily Kaplan of The MMQB, he was taken aback at the NFL combine when teams asked if he’d be able to learn an NFL playbook. “My senior year I was taking astronautics, propulsion and an aerodynamics class … all of the same day,” he told her. “At the same time as football season when I was leading an SEC team. I think I can handle it.”

2. You know Pitt quarterback Nathan Peterman? He started his career at Tennessee before he lost his job … to Dobbs. Peterman was still on the board when the Steelers took Dobbs on Saturday. Peterman made his first start as a redshirt freshman in 2013 against Florida, but was benched during the game after completing 4-of-11 passes for five yards and two interceptions. He played in four games that season, and Dobbs — a true freshman — was named the starting quarterback on Oct. 29. The next season, Peterman was benched after just two series in his only start. He was replaced by Dobbs, who kept the job from that point on. Peterman transferred to Pitt in 2015.

3. Ben Roethlisberger was at the Steelers facility the day Dobbs visited. While Dobbs was watching film in the quarterback room, Roethlisberger stopped by to say a brief hello. “It was really cool just to see him obviously,” Dobbs said on a conference call Saturday. “He’s a great football player, obviously, and I’m just excited for the opportunity to work with him and take in as much as I can from him.”
